摘要：

根据反渗透产水的特点,提出了按反渗透产水的总可交换阴离子与总可交换阳离子的比例来确定反渗透后置混床阴、阳树脂的配比,并对反渗透系统后设置脱气塔,后置阴床的OH-的累积、漏Na⁺等问题作了分析。

关键词: 水处理, 反渗透系统, 离子交换, 混床

Abstract:

Based on the characteristic of RO produced water, and according to the proportion of the total exchangeable anion (TEA) and total exchangeable cation (TEC) of RO produced water, the ratio of anion and cation resins in RO follow-up mixed bed has been determined. The problems, such as RO system follow-up degasifying column, hydroxide radical accumulation of the follow-up anion bed, Na⁺ leakage, etc. are analysed.

Key words: water treatment, reverse osmosis system, ion-exchange, mixed bed
